Key with removable head

ABSTRACT

A key with a detachable head consisting of incorporating projections ( 11 ) on the end of the shaft ( 10 ), to which projections a head ( 1 ) is coupled by means of a slot ( 5 ), which head is formed by a body ( 2 ) provided in its central area with a perforation ( 4 ) provided with a stop ( 6 ) which retains the shaft ( 10 ) to the head ( 1 ), and vice versa.

OBJECT OF THE INVENTION

The present specification refers to a key with a detachable head, whosepurpose is based on being shaped like a key capacitated for being usedconventionally after-attachment on a transversal body incorporated on akey ring which, with the collaboration of a plastic material part,permits its circular movement, this key in turn having the capacity ofbeing used in a standard manner by means of the incorporation of thedetachable head.

The head is capacitated so as to be incorporated oz removed by means ofthe coupling of a part acting as a retaining stop.

BACKGROUND OF THE INVENTION

The applicant has knowledge of the current existence of a key shaftcapacitated so as to be attached on special key rings to which they arecoupled with the collaboration of a plastic material retaining part.

However, the applicant does not know of the current existence of aninvention having the same features as those disclosed herein.

DESCRIPTION OF THE INVENTION

The key with detachable head proposed by the invention is itself shapedas a novelty, permitting its use conventionally or with thecollaboration of a key ring with suitable features.

More specifically, the key with detachable head object of the inventionis constituted as from a shaft of a metallic material which, on theupper end, is provided with a semicircular machine finishing due towhich the shaft can be inserted through a slot inside of a bodyconstituting a head, being coupled to the central perimeter bearing aperforation coupled to a stop which prevents the outward movement of thelayer, and at the same time capacitates the shaft to be moved due toactuation of the head.

On the coupling end, the shaft is provided with a smaller thickness thanthat of the total shaft body so that it can be suitably adapted insideof the head.

DESCRIPTION OF THE DRAWINGS

In order to complement the description that is being made and for thepurpose of helping to better understand the features of the invention,two sheets of drawings are attached to the present specification as anintegral part thereof, which drawings, with an illustrative andnon-limiting character, show the following:

FIG. 1 shows a frontal plan view of the upper and rear area, and at thesame time a profile and duly sectioned view of the detachable headobject of the invention, in collaboration with the shaft, forming theassembly.

FIG. 2 shows C-D views of the shaft-to-head coupling stop.

FIG. 3 shows a view of the shaft and head at the time of theirattaching.

FIG. 4 lastly shows a perspective view of the object of the invention,the shaft and head being coupled together.

PREFERRED EMBODIMENT OF THE INVENTION

In view of these figures, it can be seen how the key with detachablehead is constituted as from a head (1) and a shaft (10), the head (1)being provided with a body (2) and a central perforation (4), an upperperforation (3) for its fixing to a conventional key ring, and a slot(5) for the introducing the upper end of the shaft (10) through it,which shaft is provided with two projections (11) forming a centralsemicircular area (12) which is coupled in the perimeter of perforation(4), being retained by the actuation of a stop (6) preventing theseparation of parts (1) and (10).

In the case that the shaft (20) is to be coupled to a special key ringwhich permits its fixing with the collaboration of a plastic materialpart on its perimeter and moving in a semicircle, the shaft can beseparated from the head (1) and be used for this purpose.

1. A key with detachable head, of those constituted as from a shaft (10)which, on the upper end, is provided with a machined finishing generatedby two projections (11) which, in the central area, are provided with asemicircular area (12), this end of the shaft (10) having a thicknesssmaller than the rest of the shaft, characterized in that in the areaformed by the projections (11), a head (1) is coupled through a slot,which head is provided with a body (2) which, in the central area, has aperforation (4) in which a stop (6) is introduced, retaining the shaft(10) together with the head.
